🔊 This pack contains 25 Neural Amp Modeler (NAM) Direct profiles (DIR / Amp-only) captured from a freshly serviced Marshall 6100LM 30th Anniversary head using a controlled, studio-grade reamping and DI workflow. The goal is to deliver authentic, touch-sensitive, and mix-ready profiles reflecting the real dynamic behavior, signature British bite, and tight power-amp response of this 3-channel icon, ready to be paired with your favorite Impulse Responses (IRs).
🎚️ To maintain tonal balance across all three channels and 30th Anniversary voicings, Presence was locked at 6 (13h) for the entire collection—taming harsh upper frequencies while preserving transient definition, open high-end chime, and seamless IR integration. Power-amp Damping was strategically selected between AUTO (for organic vintage bloom) and HIGH (for locked sub-bass and razor-sharp US high-gain response).
🎛️ Gain Staging & Calibration
These profiles were captured using mathematically verified reference levels:
Input Calibration (Send): +7.5 dBu (calibrated through active reamp attenuation)
Output Calibration (Return): +10.0 dBu reference headroom
🔀 Studio-Grade Capture & Reamping Chain
The signal is routed through a precision signal chain designed to preserve pure guitar impedance, attack dynamics, and transparent A/D conversion:
D/A Conversion & Send: MOTU M4 (ESS Sabre32 Ultra DAC line out @ +16 dBu)
Reamp Box: Radial X-Amp (Active Class-A buffer & transformer isolation)
Direct Tap (DIR): Speaker output tapped into a Klark Teknik active DI running in parallel with a real reactive speaker load, preserving true power tube and transformer interaction.
Cabling: Low-capacitance, shielded cables throughout to eliminate noise floor and capacitive tone loss.

🎯 Purpose of the Pack
Designed for guitarists and producers seeking authentic, responsive 6100LM tones with zero guesswork. Simply load your preferred 4x12 cabinet IR (such as a 1960AX/BX or my 6960A to match the song of my first M6100 pack) and track directly in your DAW.
